Be careful! The motherboard might not be able to power it, that is if it only draws power from the motherboard. Even if it doesn't still be careful some of the power supplies HP puts inside their computers have proprietary connectors to the motherboard like instead of having a 24 pin you might have an 18 pin. I would do a lot of research before pulling the trigger and buying some stuff.. I have an HP Z210 workstation and it has an 18 pin connector instead of the standard 24 pin. I have a 650Ti 2GB in there and I had to under-clock it -80 on the core clock and -90 on the memory clock. The 1050Ti is definitely more power efficient than the 650Ti but still the motherboard might not supply the normal amount of power to the PCI Express...
